but it looks like it would handle a couple of kw. Writing on it:
"Amperex
4 PR 125A"

That's a 125 watt plate dissipation tube. Half that of the
4CX250s Tim already has. Max rating operated Class C
is 4 kV at 65 mA, in other words, 260 watts plate input
power, about 170 watts output power. We used to use
the 4-125A as a low level driver in our transmitters.
